The Weakest

It was then that one of the guys intervened, saying, "Who cares? Judging by how easily you destroyed the dummy, it's obvious that your cultivation doesn't reflect your real strength."

Everyone else nodded at the man's words in agreement. It turns out that even the Transition Realm cultivators couldn't destroy the dummy as easily as the twins did, so they all thought the twins were part of some big power. In other words, that meant they must have quite some treasures on them. 

Thanks to that, the people calling the twins to join were divided into three groups. Those who didn't know the path for real but wanted to use the twins' strength to complement their own. The second were the ones who thought the twins were full of treasures and wanted to lure them into a trap. And the last ones were the real groups with someone who really knew something about the Under Desert Sea and wanted their journey to be smoother with the twins' help.
